Description

Technical Field

[0001] The present invention relates to the technical field of aluminum alloy door and window processing, and specifically to an auxiliary device for welding and processing the aluminum alloy door and window frame. Background Art

[0002] The aluminum alloy door and window frame is usually assembled by diagonal welding of multiple profiles, and its welding quality directly affects the sealing performance, strength and appearance accuracy of the door and window.

[0003] When welding the aluminum alloy door and window frame, it is usually necessary to first perform diagonal splicing on the two aluminum alloy door and window frame borders, and then use a welding machine to weld the front and back of the diagonal splicing joint formed by the two aluminum alloy door and window frame borders. Then, diagonal welding is performed on the other two aluminum alloy door and window frame borders. Finally, the two are welded together to form the aluminum alloy door and window frame. The stability of the aluminum alloy door and window frame border during welding is directly related to its welding quality. If the two aluminum alloy door and window frame borders shift and misalign during welding, it will cause welding errors and affect the welding quality.

[0004] In order to reduce welding errors, currently, a clamping structure is often used to assist in clamping and positioning the aluminum alloy door and window frame to be welded. This process first requires manual diagonal splicing of the two aluminum alloy door and window frame borders, and then clamping and positioning the spliced two aluminum alloy door and window frame borders. However, this operation is relatively cumbersome. The aluminum alloy door and window frame is usually a rectangular structure, so the lengths of the two aluminum alloy door and window frame borders for diagonal splicing are often different. It is difficult to directly position the diagonal positions of the two aluminum alloy door and window frame borders during manual splicing and requires repeated adjustment. Moreover, when manually using the clamping structure for clamping and positioning after diagonal splicing, small offsets will occur at the diagonal of the two aluminum alloy door and window frame borders due to shaking, resulting in still offset and misalignment problems and affecting the welding quality. Summary of the Invention

[0005] The purpose of the present invention is to provide an auxiliary device for welding and processing the aluminum alloy door and window frame to solve the problem that it is difficult to quickly position the diagonal splicing joint when the two aluminum alloy door and window frame borders with different lengths are diagonally spliced by the current auxiliary device for welding and processing the aluminum alloy door and window frame.

[0024] Embodiment

[0025] As Figures 1 to 5 shown, an embodiment of the present invention provides an auxiliary device for welding and processing an aluminum alloy door and window frame, including a processing platform 1, and further including two groups of clamping and conveying devices, which are arranged on the top of the processing platform 1, respectively arranged along the first direction and the second direction of the processing platform 1, and the first direction and the second direction are perpendicular. In actual implementation, the first direction refers to the length direction of the processing platform 1, and the second direction refers to the width direction of the processing platform 1. The clamping and conveying device includes a positioning mechanism, a clamping mechanism and a conveying mechanism; the positioning mechanism includes a limit block 4 and a sliding component, the sliding component is arranged on the top of the processing platform 1, and the limit block 4 is connected with the sliding component. The limit block 4 is used to position the door and window frame border to be welded before clamping and conveying; the clamping mechanism is arranged on one side of the positioning mechanism, including a clamping plate 21 and a linear movement component 22, and the moving end of the linear movement component 22 is connected with the clamping plate 21; the conveying mechanism includes a plurality of conveying rollers 3 and a rotation driving component for driving the conveying rollers 3 to rotate. The plurality of conveying rollers 3 are arranged in parallel on the opposite side of the clamping mechanism, and are used for conveying by the plurality of conveying rollers 3 when the linear movement component 22 drives the clamping plate 21 to move and clamp the door and window frame border against the plurality of conveying rollers 3.

[0026] In this embodiment, when performing diagonal welding on the door and window frame, referring to Figure 1 , first place the two door and window frame borders to be spliced into two groups of clamping and conveying devices respectively, so that the door and window frame borders to be spliced are located between the clamping plate 21 and the two conveying rollers 3, and make the ends of the door and window frames to be spliced abut against the limit blocks 4, so as to ensure that the two are in the same starting position. Then drive the clamping plate 21 to move through the linear movement component 22, so that the clamping plate 21 abuts against the door and window frame border, and realize the clamping and positioning of the door and window frame through the cooperation with the two conveying rollers 3. Then move the limit block 4 away through the sliding component to release the limit on the door and window frame, referring to Figure 4 . Then, by simultaneously controlling the rotation of the rotation drive components of the two groups of clamping and conveying devices, drive the two conveying rollers 3 in each clamping and conveying device to rotate respectively. During the rotation of the two conveying rollers 3, the door and window frame will be driven to move by friction, so that the two door and window frames to be spliced move simultaneously in the first direction and the second direction, splice the diagonals of the two door and window frames together, and then control the rotation drive component to stop rotating and keep the current splicing position unchanged, so as to use a welding machine to weld the diagonals of the two spliced door and window frames. In the whole process, by controlling the initial positions of the two door and window frames to be the same and synchronously using the two groups of clamping and conveying devices to convey the door and window frame borders, they can be accurately spliced together. After welding, loosen the clamping plate 21 through the linear movement component 22 so as to remove it.

[0027] Specifically, as shown in Figure 1 and Figure 2 , the linear movement component 22 includes a mounting seat 221, a U-shaped frame 222, a lead screw 223 and a threaded sleeve 225; the mounting seat 221 is fixed on the top of the processing platform 1; the U-shaped frame 222 is fixed on the side of the mounting seat 221 facing away from the clamping plate 21; the lead screw 223 is rotatably connected to the U-shaped frame 222, and one end of the lead screw 223 is connected with a rotating part 224 for driving its rotation; one end of the threaded sleeve 225 is threadedly connected to the lead screw 223, and the other end of the threaded sleeve 225 passes through the mounting seat 221 and is fixed to the clamping plate 21.

[0028] In this embodiment, when driving the clamping plate 21 to move through the linear movement component 22, drive the lead screw 223 to rotate by controlling the rotating part 224. The rotation of the lead screw 223 is converted into linear movement through the cooperation with the threaded sleeve 225, so as to drive the clamping plate 21 to move through the threaded sleeve 225 to realize the clamping process.

[0029] Among them, the rotating part 224 is a self-locking handwheel. By setting the self-locking handwheel, the position of the two door and window frames can be locked after their diagonals are spliced, so as to avoid deviation during the welding process.

[0030] In another embodiment of the present invention, in order to make the clamping plate 21 move more smoothly on both sides when it moves, guide holes are provided on the side walls of the mounting seat 221 on both sides of the threaded sleeve 224. The guide holes are parallel to the threaded sleeve 224. A slide bar 225 is slidably connected in each guide hole, and one end of the slide bar 225 is connected to the clamping plate 21.

[0031] In another embodiment of the present invention, a lubricating coating is provided on the clamping surface of the clamping plate 21. The lubricating coating can be a solid lubricating coating such as graphite or molybdenum disulfide, which is fixed on the clamping surface of the clamping plate 21. By providing the lubricating coating, the frictional resistance generated when the clamping plate 21 clamps the frame of the aluminum alloy door and window can be reduced, so as to drive the movement of the frame of the door and window by the rotating conveying roller 3.

[0032] In another embodiment of the present invention, as Figure 1 and Figure 3 shown, the sliding assembly includes a rack 51 and a first gear 52; the rack 51 is vertically fixed on the side wall of the clamping plate 21; the first gear 52 is rotatably connected between the rack 51 and the limit block 4. A plurality of meshing teeth are provided on the side wall of the limit block 4 facing the first gear 52. Both the rack 51 and the limit block 4 are meshed with the first gear 51. A chute 11 is provided at the top of the processing platform 1, and the limit block 4 is slidably connected in the chute 11.

[0033] In this embodiment, by providing the sliding assembly composed of the rack 51, the first gear 52 and the limit block 4 provided with a plurality of meshing teeth, when the clamping plate 21 moves along with the linear moving assembly 22, through the gear-rack meshing transmission, it can drive the limit block 4 to move along the chute 11 in the opposite direction of the clamping plate 21, so as to automatically release the limit on the frame of the aluminum alloy door and window, facilitating the subsequent movement of the frame of the aluminum alloy door and window driven by the conveying roller 3.

[0034] Specifically, as Figure 1 shown, there are two conveying rollers 3 in the conveying mechanism, including a rotation driving assembly including a rotation driving part and a first synchronous belt transmission structure 6; the rotation driving part is arranged at the bottom of the processing platform 1. In a specific implementation, the rotation driving part is a driving motor. The roller shaft of one of the conveying rollers 3 extends to the bottom of the processing platform 1 and is connected to the output end of the rotation driving part; the first synchronous belt transmission structure 6 is connected between the roller shafts of the two conveying rollers 3.

[0035] By providing the rotation driving part, it can drive one of the conveying rollers 3 to rotate. Since the roller shafts of the two conveying rollers 3 are connected by the first synchronous belt transmission structure 6, the first synchronous belt transmission structure 6 can be used to realize the function of synchronous rotation, thereby driving the two conveying rollers 3 to rotate synchronously.

[0036] In another embodiment of the present invention, in order to facilitate the synchronous movement of the conveying mechanisms of the two clamping and conveying devices, a synchronous driving assembly is provided between the conveying mechanisms of the two clamping and conveying devices. The synchronous driving assembly includes two transmission shafts 71, two second gears 72, and two sets of second synchronous belt transmission structures 73. The two transmission shafts 71 are vertically rotatably connected to the top of the processing platform 1. The two second gears 72 are respectively sleeved and fixed on the two transmission shafts 71, and the two second gears 72 are meshed with each other. For the two sets of second synchronous belt transmission structures 73, one set of second synchronous belt transmission structure 73 is connected between one of the transmission shafts 71 and the conveying roller 3 in one of the conveying mechanisms, and the other set of second synchronous belt transmission structure 73 is connected between the other transmission shaft 71 and the conveying roller 3 in the other conveying mechanism.

[0037] In this embodiment, since there are two transmission shafts 71 and two second gears 72, the reverse transmission function can be achieved. Moreover, the conveying roller 3 in each conveying mechanism is connected to the transmission shaft 71 through the second synchronous belt transmission structure 73, so that Figure 4 for example, when the rotation driving part drives the two conveying rollers 3 in the upper left conveying mechanism to rotate clockwise, through the reverse rotation generated by the second synchronous belt transmission structure 73 and the meshing of the two second gears 72, the two conveying rollers 3 in the lower right conveying mechanism will be driven to rotate synchronously and counterclockwise, so as to drive the two window and door frames to be spliced to move horizontally to the left and vertically upward respectively and then be spliced together.

[0038] The above-disclosed are only several preferred specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present invention.
